Jeep Technology has long been synonymous with rugged durability and off-road prowess. However, the brand’s success isn’t just about tough exteriors; it’s deeply rooted in continuous technological innovation. This article explores the key areas where Jeep has pushed the boundaries of automotive technology, from its legendary 4×4 systems to its foray into electrification.
Evolution of Jeep’s 4×4 Systems
Jeep’s 4×4 systems are at the heart of its off-road capability. These systems have evolved significantly since the brand’s inception, becoming more sophisticated and versatile.
Early 4×4 Systems
The original Willys MB featured a simple, robust 4×4 system with a two-speed transfer case. This basic setup laid the foundation for future innovations.
Modern 4×4 Systems
Today, Jeep offers a range of advanced 4×4 systems:
| System | Key Features | Models |
|---|---|---|
| Command-Trac | Part-time 4WD, 2.72:1 low range | Wrangler, Gladiator |
| Rock-Trac | Part-time 4WD, 4:1 low range, locking differentials | Wrangler Rubicon, Gladiator Rubicon |
| Quadra-Trac I | Full-time 4WD, single-speed transfer case | Grand Cherokee |
| Quadra-Trac II | Full-time 4WD, two-speed transfer case | Grand Cherokee, Wagoneer |
| Quadra-Drive II | Full-time 4WD, electronic limited-slip differential | Grand Cherokee, Wagoneer |
Selec-Terrain System
Introduced in 2011, the Selec-Terrain system allows drivers to optimize vehicle performance for various conditions (Auto, Sand, Mud, Snow, Rock). This system works in conjunction with the 4×4 drivetrain to provide optimal traction in any environment.
